IFCIDS for Db2 z/OS Audit

WLX Audit for Db2 z/OS works solely with IBM Technology. It gathers all static & dynamic SQLs from EDM & DSC Caches by STC to OPx and efficiently uses IFCIDs 23, 24, 25, 62, 90, 91, 140, 141,142, 143, 144, 219, 220, 316, 318, 400, 401

There are hundreds of IFCIDs that you can start and use for Db2 z/OS Audit or performance monitoring. Some come very cheaply like the 316, 317, 401 some are very CPU expensive like the 58 (SQL Full Trace). WorkLoadExpert (WLX) does not use the following IFCIDs for this very reason.
